To all If/0m 'it may concern:

lie it known that l, EDWARD SIEBAGH- Minna, a. citizen ot the UnitedStates, and resident of lVest Hoboken, in the county of lludson andState ot New Jersey, have invented new and useful Improvements inll'lechanisms tor Stopping lVIOtOr-Vehieles, of which the following' isa specification.

lily invention relates to imj'novelnents in mechanisms for stoppingmotor vehicles and .it consists in the combinations. arrangements, andconstructions herein described.

iin object ot my invention is to provide novel stopping` shoes` designedto be carried b v the vehicle and to be cast to the road in positiont'or the vehicle driving wheels to run upon the same, so that thewheels, instead ot revolving' or skid'ding` on the road, will besupported upon the shoes which are provided with means tor gripping' theroad. Another object ot the invention is to pro vide operating mechanismby which the.

chautleur, as he sits in his customary place by.

theI steering` wheel, maj' quickly ,etlcc-t either a service applicationor a release o'l" the shoes; and turthento provide a novel connectionbetween this mechanism and the clutch pedal whereby. when a serviceapplication is made, the clutch pedal will be automatically operated tounclutch the transmisi sion. the arrangement ot the connection being'such that when the shoes are released or are in non-service position.the clutch pedal will be tree to be operated in the usual wav withoutproducing,r an etfcct upon the shoe operating` mechanism.

A. further object is to provide al constrluftion in which when a serviceapplication ot1 the shoes is made and the clutch pedal is actuated touncluteh the transmission. the Ishoe operating mechanism may be lockedto prevent the thet't ot the vehicle or its use by unauthorized parties.

@ther objects and advantages will appwar in the following specificationand the novel 'features of 'the mechanism will be particui lai'lypointed ont in the appended claims.

(lne ot the many possible embodiments ot the invention is illustrated inthe accompanj'ing drawings forming a material part ot thisspecification. and in which Figure l is a side elevational view withparts in section. ot a. stopping mechanism constructed in accordancewith the present. invention. includinga a fragment oi an auto- Imobileshown in broken lines. ln this View,

the parts ot the mechanism are shown in the relative positions thejYoccupy when the stopping shoes are moved into service position.

Fig. 2 is a similar view, but showin@ the bile, shown in broken lines.In referring to the parts of the automobile, let the numerals 10 and 1ldesignate the steel side sills ot the framework: 12 and 13 the rearground or drivin.;v wheels which are provided with the usual pneumatictires; l1- the rear axle: l5 and 1li the t'oot boards; 17 thechai'lflfeilfs seat: and 1S the steering post with the usual steering'wheel 19.

llolted to and depending' ilrom each ot the sills 1() and 11 is a hangerQ0. in which is arranged ior turning' or rocking movement a cylindricalbearing' device 21. formed at its outer end with a cjlimlrical portionprojecting at a right-angle. The bearing' devices 21. are holedlongitudinalljv to re ceive the ends ol a roch sha t't 23. The ends oithe rock sha'tt are preterablv formed to have anti-turning lit in thebearing devices. although they may be pinned or otherwise rigidlyvsecured thereto. so that the bearing' devices,l will be moved togetherin accordance with the rocking movements ot the shait.

Each projecting portion 22, as clearly illustrated in Fig'. Il. isprovided with a reduced part :2lhavinjga central bore Mounted on thereduced part 2l and secured thereto by set screws )tV or otherwise, is acylindrical casingr 2l having` an opening` 28 in its bottom. "Working inthe bore and through the opening' '28 is a pin or plunger 21) formedwith a collar 2:50 in position to limit its` outward movement. lllountedaround the plunger is a push spring' 31. which. beinel engaged betweenthe end ot Qt and the collar, normal lj' urges the plun` seated a rubberbleek or plate 81 having any suitable projecting eontigurations as 82,kadapted to grip or take hold of the road. So that it may be readilyreplaced when impaired through wear, the rubber block is removablysecured to the base by screws as 83 or other suitable means.

Having thus described my invention, What I claim is 1 'In a motorvehicle having a driving wheel, a stopping shoe adapted to take hold ofthe road and to receive and support said shoe, a rock shaft having` acrank and having also means to attach and suspend the shoe position tobe brought into and out ofvengagenient with the driving wheel at thepoint of its engagement with the road, means for guiding said shoe, anaxis and an operating lever movable thereon into on or off position` aconnection between said operating lever and the rock shaft crankwhereb)v to swing said shoe into or out of engagement with the wheelaccordingly as said lever is moved into on or "ott"7 position, a curvedlever pivoted to said operating lever and provided with a tooth, a hubdevice loose on saidaxis and provided with a tooth and an arm, a clutchpedal and a shaft roekablel therewith, linkage connection between saidhub arm and said elut-eh pedal shaft through which the hub may beactuated freely b v the clutch pedal when the operating lever is in offposition.v said operating` lever through the engagement of the curvedlever tooth with the l1iibtooth serving as means, when moved int-o onposition, for autoniatically actuating said eluteh pedal.

i aln a motor vehicle, the combination with :i driving wheel and aclutch pedal oontrolling the clutching and unclutching of thetransmission, of a stopping shoe adapted to take hold of the road and toreceive and support the drivingwheel, a rock sha-ft having a crank andhaving also means to attach and suspend the shoe in position to bebrought into and out of engagement with the wheel at lthe point of itsengagement with the road, an axis, an operating lever movable thereon,into on or off position, a connection between said lever and said crankby which to swing said shoe into or out of engagement with the drivingwheel accordingly as said operating lever is moved into on7 or oftposition, a curved lever pivoted to the operating lever and providedwith a tooth, a hub on said axis and provided with a tooth,- linkageconnection between said hub and said clutch pedal whereby movement ofeither one will effect the actuation of the other, the said hub beingfreely movable when the operating lever is in off position, saidoperating lever when moved into on position serving as the means throughthe engagement of said curved lever tooth with the hub tooth forautomatically actuating the clutch pedal.

3. In a motor vehicle, the combination with an operating lever movableon a shaft into Kon or ott77 position and a clutch pedal movable with ashaft into on or off position, of a curved lever pivoted to saidoperating lever and provided with a tooth, a hub mounted on saidoperating lever shaft and provided with a tooth and an arm,lilikageJconnection between the hub arm and the clutch pedal shaftwhereby either the hub o the clutch pedal may be actuated upon themovement of the other, said hub, when the operating lever is in offposition, being movable to allow the clutch pedal to be moved freelyinto on or off position, the said operating lever when moved into onposition serving as the means through the engagement of the curvedlever' tooth with the hub tooth for automatically effecting the movementof the clutch pedal into off position.

In testimony whereof I have signed my name to this specification.

EDVVARD SIEBACHMEIER.
